Biodiesel has been gaining increased attention as a nontoxic, biodegradable and renewable new green alternative diesel fuel. Production of biodiesel can be synthesized by chemical or by lipase methods, while lipase method has more advantages compared to chemical synthetic method. In this article, the microbial strains with activity of lipase were isolated from long time oil-contaminated soil and strain...
Used Tween-80 as emulsifler, industrial lipase as catalyst to hydrolyze waste oil from restaurants and make mixed fatty acid. We discussed the enzyme concentration, substrate concentration, temperature and time on hydrolysis. Through the experiment, we found that when we used emulsifier which contains 2% oil in the system, we could get the optimal parameter for hydrolysis of waste oil from restaurants...
In this research, results of an experimental study of prickly ash seed cust oil on the preparation of fatty acid methyl ester by lipase catalysis were presented. Factors such as n-hexane, the FAME rate, water concentration, volume of lipase, et al were studied. The experiment results showed that n-hexane is most suitable solvent in the non-aqueous lipase catalytic system and the FAME rate reach the...
A novel approach to the surface functionalization for membraneless enzymatic glucose/oxygen biofuel cell applications is described. The biofuel cell employs the gold plate electrodes modified by specific graphene-enzyme conjugations, which are immobilized by electrochemical deposition of the conducting polypyrrole polymer. The electrochemical activity of these electrodes is superior to the electrodes...
Biofuel cells are considered the most promising future energy source. This paper presents a bio-energy generation system based on the micro-fluidic platform which utilized enzymes as catalysts and glucose as a fuel to process the electrobiochemical energy conversion and storage in a cell. This is known as the enzymatic bio-fuel cell (EBFC). It is designed to consist of two modified gold electrodes...
